To all whom. fr' Ebay concern.-

Be it known that I, JOHN MCE. AMES, a citizen of the United States, and a residentof New Brighton, in the county of Richmond and State of New York, have invented certain new and useful Improvements in Car-Truck Bolsters, of which the following;V is a specification.

The invention relates to improvements in car-truck boisters'; and it consists in the novel features and combinations of parts hereinafter described, and particularly pointed out in the claims.

The object of the invention is to produce an integral cast bolster of novel formation and which shall be ecient and convenient of use and have its parts so disposed as to secure the maximum o'f strength with the minimum weight and enable the casting of the bolster with the least possible labor, diiiieulty, and expense.

The invention will be fully understood from the detailed description hereinafter presented, reference being-` had to the accompanying drawings, in whicin- Figure 1 is a side elevation, partly broken away and partly in section, of a car-truck bolster constructed in accordance with and embod ying' the invention, about one longitudinal half of the bolster being' shown in central vertical section on the dotted linel 1 of Fig. 2. Fig. 2-is a top view oi' same. Fig. 3 isa vertical transverse section of same on the dotted iine 3 3 of Figa 2, :1nd Fig'. ft is a vertical transverse section of sann'e on the dotted line 1L 4 of lie- 2.,

in the d rawings, 10 designates the bolster ne: i: whole, and iid bolster wiil preferably be in one integr-:ii hoilow casting and equipped with the center hearing ll and transverse plains l2 forappropriate side hearings or rubirons.

The bolster iii is subsnntinlly uniform in width, horizontuiy considermi, freni end to end, and in depth ,grnilnniy les-sens from its center toward its end poriioiis, the Lipper and lower outlinnsof the bolster converging' from ihn center toward the ends thereof.

'l'he body ol' i-hc bolster comprises the vertirnl sides lvl und tnpwnil i5, said body being' l opi-.n hroughont thi `greater portion oi. its extent at its haver sidi.` or bottoni, :1nd said sides il and lop i5 iwi connected by a series ol iran. Wielrs li.

(h: the vnrtiwd sides' of nach end portion ol l taudis 1%? and central longitudinal 21, located upon a channel or sand-plank 2.2.

The recesses for the wooden blocks 20 are formed belowv the top 1 band between the sides 14, end webs 16, and vertical bolster ends 23, as shown in Fig. 1, and the ends of the bolster about said recesses are somewhat wider than the other portions thereof, as represented in At the central portion of the bolster is ai novel box-like formation upon whose pper surfaces is the circular vertical fiange 24,. defining the center bearing, and which box-like structure extends upwardly above th e fg'eneral top 15 of the bolster and exteriorly comprises the sides 14 and vertical Walls 25, ex tending upwardly from the top 15 to complete the circular outline of said box vand support the flange 24 and top wall 26. At the center of the circle defined by the Hangs-24 is provided theintegral sleeve 27 for the usual. king-bolt, this sleeve projecting slightly'above and materially below the top wall 26, and the lower end of said sleeve terminating at a p'oint intermediate the bottom and top of the body of the bolster, as shown in Fig. 1. 'Within the bOX'- like strueturcat the center of the bolster are the substantially semicircular transverse Webs 28, which connect the sides 14 and top 15 and are directly below the exposed. end Walls 25 of said structure, and within vsaid structure the walls 25 and webs 28 are connected with cach other and with t e sleeve 27 and top A26 by a series of longitu nalwehs 29 and transverse webs 30, as shown in Fig. 2, whereby the said structure is rendered strong and durable and the sleeve 27 becomes lirmly sus' tained.

From the end walls 250i' the center bearing structure vertical parallel ianges 3l extend to the` ends of the bolster, said [langes 31 being "integral with the top 15 and at points mtermediate the center bearing and ends of th e bolster extending' upwardly above their general outline and supporting the transverse -plates 12 to receive suitable side bearings, said plates 12 being integral with both of said @,nges 31 and extending laterally beyond the same and supported at their end portions by webs 32, which-are integral with said plates and said flanges. The ends of theplates 12 are suitably apertured to receive the rivets or bolts :for securing an appropriate bearingplate 33.

l Between the sides 14 of the bolster lprovide at each side of the center structurea longitudinaLweb 17, above referred to, which ex- L tends from the outer end web 16 to the web 28 of' the centerbearing structure, and these 'webs 17 are integral with the top 15 and webs 16, as represented by the dotted lines in Fig. 2, and are in line withfthe central webs 129 of the'center bearing structure. 'i

' The body of the bolster is preferably entirely open at its lower side for convenience in casting.

What'lc'laim as my invention, and desire to 1. As a new article oli' mannfacture the integral hollow castbolster comprising the body having the sides and top and at its center Ia box-like structure for a center bearing, said structure extending above the body of the bolster, and the longitudinal flanges extending from the upper portion of saidb'ox to the end portions of the bolster and affording seats forv side bearings; substantially as set forth. 2. As a new article of manufacture, the integral hollow cast bolster comprising the bodyhaving the sides and top and at its center av box-like structure for a center bearing, said 'structure extending above the body' of the bolster, and the said body being openat-its lower side and containing the series of trans.- verse webs and longitudinal web, and the top of said body having the longitudinal flanges extending from said box to the end portions` of the bolster; substantially as set forth.

3'. As a new article of manufacture, the integral hollow cast bolster comprising the body. 'having the sides and top and at its center a box-like structure for a center bearing, said structure extending above the body of the bolster, and thelongitudinal flanges extending from the upper portion'of said box to the end portions of the bolster and affording seats for side bearings, said box structure comprising-the sides, top, end lwalls extending to the bottom of the bolster, central sleeve and longitudinal and transverse webs connecting saidparts; substantially-as set forth.

bearings; substantially asset forth. I

5. As a new article of manufacture, thefintegral'hollow cast bolster com rising the body.

having the sides and top an at its center a .box-like structure for a center bearing, said structure extending' above the body Aoffthe bolster, and the longitudinal lianges extending from the, upper portion of said box to thev end portions of the bolster and having integral therewith the transverse plates for side bearings, said plates being extended beyond said flanges and-supported at their ends by webs integral therewith and with said flanges;

substantially as set forth.
